The Military Armament Corporation MAC 1014 Marine is a 12 Gauge semi-automatic tactical shotgun built around a self-regulating gas piston system. Its 18.5-inch barrel and 5+1 capacity provide a practical configuration for defensive and tactical applications, while the nickel finish adds corrosion resistance. A receiver Picatinny rail supports compatible optics and accessories, and the ghost ring rear sight with blade front sight provides a fast, durable aiming system. The 3-inch chamber accepts a broad range of shotshell loads, and Benelli Mobil Choke compatibility allows users to tailor the pattern with compatible choke tubes.
